First beams for ISOLDE target

11 March 1974

In March 1974, the SC improvement programme is completed and the first beams are directed towards the ISOLDE targets. 

The intensity increase of the external beam up to 1 μA together with new target designs hold their promises and give a considerable increase in the number of isotopes available for experiments.

A new target design and a new layout of the isotope separator is implemented. The target-ion-source unit is placed in the proton beam and the magnet of the isotope separator is placed close to the target. The separated isotopes are then directed towards the experimental setups via a switchyard, which allows researchers to experiment with isotopes of different mass numbers simultaneously.

The first experiment at the reconstructed ISOLDE Facility was performed on March 11, where a target-ion-source system for production of neutron deficient Cs isotopes was used to detect combined beta-delayed proton and alpha emission for the neutron deficient Cs isotopes with mass numbers 118 and 120.
